JavaScript code

Question

So I have been working with some codes and input event but sometimes I have to face the same issue everytime. My input result is cleared by default, but once I type a value it will give me the result I want and that's great, but once I erase the input field, it has a number because the function is taking an empty field as a 0. Can anybody tell me how to get rid of that? Thanks in advance.

Answer 1

Like this?

const inputCelcius = document.getElementById('inputCelcius');

inputCelcius.addEventListener('input', function CelciusToFahrenheit(celcius){
const fahrenheit = ((celcius.target.value * 1.8) + 32);
const returner = document.getElementById('returnCelcius');
if (inputCelcius.value.length == 0)
{
returner.value = null;
}
else
{
returner.value = fahrenheit;
}

})
